Why should we learn React JS ? Many of us might got the same doubt. Right? Let’s know some reasons to learn React JS.
This isn’t just a numbers game. It’s surprising that moving UI operations to virtual DOM actually changes how your application feels for the end-user. You’ve probably already started noticing this phenomenon across the web on websites such as Netflix.
React supports modular design that is often associated with building large, scalable applications. The reason for this is the advent of EcmaScript 6 specification that came out in 2015 which provides new syntax that favors modular methodology.
For example, the required (ES5) and includes (ES6) keywords tie together not only files alone but assume a class-based relationship between objects.
And even though as of this writing include keyword is not supported in modern browsers (even Chrome) we can begin writing modular programs by either using require or transpiring our ES6 code to ES5 (that almost all browsers do understand by now) before sending it to the browser for rendering.
In React each HTML element is treated like a programmable component that can be nested within other compo nested. Child components have parent components associated with them.
React is more than just a UI view library as opposed to what you will probably hear at first when you start figuring it out. And that isn’t entirely wrong. React gives us the ability to create lightning-fast interactive components that can be used as elements of your application.
However, React’s utilizes the principle of render targets which allows you to send the result of your code to just about anywhere, included but not limited to front-end view.

When you are learning React, you are learning computer programming principles, not just a list of functions and methods, which is the case with other libraries such as jQuery.
